AX7DBF1-2000.0000C Equivalent & Substitute Parts

Part Overview

The AX7DBF1-2000.0000C is a 2 GHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC as part of the ClearClock™ AX7 series. This surface mount oscillator operates at 2.5V supply voltage with Enable/Disable functionality, housed in an 8-SMD, No Lead package measuring 7.00mm x 5.00mm. The part is discontinued at DiGi Electronics, making identification of equivalent alternatives essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF1-2000.0000C is determined by the following critical parameters:

• Frequency: Must be 2.0000 GHz
• Output Type: Must be LVDS
• Package Type: Must be 8-SMD, No Lead with identical footprint dimensions (7.00mm x 5.00mm)
• Function: Must support Enable/Disable capability
• Frequency Stability: Must meet ±25ppm specification
• Operating Temperature Range: Must cover -40°C ~ 85°C
• RoHS Compliance: Must maintain ROHS3 Compliant status

The AX7DCF1-2000.0000C qualifies as a substitute based on matching all critical parameters. The primary difference is the supply voltage specification: the substitute operates at 1.8V instead of 2.5V. This voltage difference requires circuit-level evaluation to determine compatibility with the original design's power supply architecture.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7DBF1-2000.0000C and AX7DCF1-2000.0000C maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, eliminating moisture-related handling constraints.

The primary selection criterion is supply voltage compatibility. The main part operates at 2.5V, while the substitute operates at 1.8V. Selection of the substitute requires verification that the design's power supply architecture can accommodate 1.8V operation and that all downstream circuitry connected to the oscillator output is compatible with 1.8V LVDS signal levels.

Both parts are discontinued at DiGi Electronics. Inventory availability should be confirmed through authorized distributors before final procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-2000.0000C directly replace the AX7DBF1-2000.0000C?

A: Direct replacement requires verification of 1.8V supply voltage compatibility in your circuit design. The substitute operates at 1.8V instead of 2.5V. If your power supply and signal chain are designed for 2.5V operation, the substitute will not function without circuit modifications.

Q: Are the package footprints identical?

A: Yes. Both parts use 8-SMD, No Lead packaging with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB footprints are interchangeable.

Q: Do both parts support Enable/Disable functionality?

A: Yes. Both the AX7DBF1-2000.0000C and AX7DCF1-2000.0000C include Enable/Disable control capability.

Q: What is the frequency stability specification for both parts?

A: Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: Are there moisture sensitivity concerns with either part?

A: No. Both parts carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity limitations during storage or handling.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
